If, upon verdict or demurrer, the court believe that the patent or grant was made against law or obtained by fraud, surprise, or upon untrue suggestions, it may vacate the same; and a copy of such judgment, after being recorded at large, shall be filed by the petitioner in the Secretary of State's office, where it shall be recorded in a book kept for that purpose; and the Secretary shall note in the margin of the original record of the grant the entry of the judgment, with a reference to the record in his office.
